Did you follow the instructions exactly word by word and step by step as listed?

Also, as mentioned in my post, there could be programs other than Skype and Google Chrome that may have a similar issue and causing the heightened disk activity. Have you confirmed its only Skype and Google Chrome causing the 100% disk activity?

Are you using a genuine and activated copy of Windows 10? Google Chrome has another setting in the advanced section called "Protect you and your device from dangerous sites" this will cause high disk activity if either your computer is infected with a virus
or has either bootleg versions of Windows or Office. Please check your computer for potential viruses and / or trojans / Worms / Adware etc.

Another good place to see what may be going on is the Windows System and Application event log.

Please do not quote the whole post, especially if you have nothing to add to it.

I add a SOLUTION: NOT PERMANANT but can be kept on being done.

Type on search "view local services" select "Background Intelligent Transfer Service" stop it and go to properties and select disabled it will hold more a less a day it will take 2 or 3 minutes to stop disk at 100% usage.

Disabling an integral system service is ill advised. You need to figure out the real cause of the high disk usage and then resolve that problem. I will recommend you use msconfig to run in safe boot mode with networking and also disable all non microsoft
services in the services tab and then see if it resolves the issue, if it does then start enabling one service at a time to find out which causes the problem to appear again.

I use Firefox and don't have Skype running. I stopped Background Intelligent Transfer Service and Superfetch as suggested, so now my disk use is down from 100% to 85% as I write.

The hog when I start up is OneDrive (which has had numerous problems since I upgraded to Windows 10) then it's this retinue of "Service Host: Local System" with all sorts of services that I doubt I need on a laptop.

I've turned off everything extraneous, including the P2P updates, and still have the problem. My fan is constantly running, even when HDD use is finally down 5%. This issue is SO frustrating and has umpteen solutions on the internet (including here) that
I'm getting ready to revert back to Windows 7. It's a workhorse that works.
